已经证明，圬工拱桥的荷载-挠度响应通常主要是土壤响应的函数。因此，特别是考虑到目前缺乏合理的和广泛接受的砌体拱桥的正常使用标准，本文探讨了一种方法来估计砌体拱上的压力，从而正常使用的负载能力。由于桥梁评估工程师必须同时考虑正常使用和极限状态，因此研究了将欧洲规范7中的相关原则应用于圬工拱桥的可能性。对无粘性回填土试拱的参数研究表明，根据回填土强度的不同，稳定性既可由正常使用极限状态控制，也可由极限状态控制。相比之下，目前英国标准的评估公路桥梁和结构，BD 21，似乎是过于保守的低强度回填。科林·C Smith，Matthew吉尔伯特和Philip A.马蹄莲
It has been demonstrated that the load-deflection response of a masonry arc h bridge may often be primarily a function of the soil response. Consequently , and particularly given the current lack of rational and widely accepted serviceability criteria for masonry arch bridges, this paper explores an approach for estimating serviceability s o l pressures on a masonry arch and thus a serviceability load capacity. Since bridge assessment engineers must consider both serviceability and ultimate limit states, the possi bility of applying the relevant principles from Eurocode 7 to masonry arch bridges is examined. Param etric studies on a sample arch with cohesionless backfill indicate that stability ma be controlled by either the serviceability limit state or ultimate limit state, depending on the backfill strength. In comparison, the current UK standard for the Assessment of Highway Bri dges and Structures, BD21, appears to be overconservative for lower strength backfills . Colin C.
